This text covers the computation of current ratings of electric power cables, a procedure essential in the determination of the maximum current a power cable can carry without overheating. It also helps engineers determine the cable size and type in order to prevent the need for re-installation.
Rating of Electric Power Cables in Unfavorable Thermal Environment is the first text to provide you with the computational tools and techniques needed to successfully design and install power cables in areas affected by such factors as outside heat sources, ground moisture, or impediments to heat dissipation. After thoroughly reviewing standard rating models, the author discusses several new techniques designed to improve cable ampacity, as well as new computational techniques for analysis of cyclic loads. To facilitate computational tasks he utilizes six representational model cables throughout the book, including transmission-class, high-voltage, distribution, and bundled types. End-of-chapter summaries, liberal numerical examples, and practical, real world applications make this text a valuable resource for making better design and operation decisions.
A guide to the physics of Dynamic Temperature Sensing (DTS) measurements including practical information about procedures and applications Distributed Fiber Sensing and Dynamic Ratings of Power Cable offers a comprehensive review of the physics of dynamic temperature sensing measurements (DTS), examines its functioning, and explores possible applications. The expert authors describe the available fiber optic cables, their construction, and methods of installation. The book also includes a discussion on the variety of testing methods with information on the advantages and disadvantages of each. The book reviews the application of the DTS systems in a utility environment, and highlights the possible placement of the fiber optic cable. The authors offer a detailed explanation of the cable ampacity (current rating) calculations and examines how the measured fiber temperature is used to obtain the dynamic cable rating information in real time. In addition, the book details the leading RTTR suppliers, including the verification methods they used before their products come to market. Information on future applications of the DTS technology in other aspects of power system operation is also discussed. This important book: • Explains the required calibration procedures and utility performance tests needed after the installation of a DTS system • Includes information on the various practical aspects of communicating measured and computed quantities to the transmission system operator • Reviews possible applications of the technology to fault location, vibration monitoring, and general surveying of land and submarine cable routes Written for cable engineers and manufacturers, Distributed Fiber Sensing and Dynamic Ratings of Power Cable is an authoritative guide to the physics of DTS measurements and contains information about costs, installation procedures, maintenance, and various applications.
Electrical Power Cable Engineering, Second Edition remains the foremost reference on low- and medium-voltage electrical power cables, cataloging technical characteristics and assuring success for cable manufacture, installation, operation, and maintenance. While segments on electrical cable insulation and field assessment have been revamped to reflect industry transformations, new chapters tackle distinctive topics like the location of underground system faults and the thermal resistivity of concrete, proving that this expanded edition lays a sound foundation for engineering decisions. It deconstructs the external variables affecting conductor, insulation, and shielding design.
Power Cable Technology provides a precise understanding of the design, manufacture, installation, and testing of a range of electric power cables—from low-voltage, 1,000/1,100V cables to extra-high-voltage, 400kV cables—with reference to future trends in the industry. The authors’ mantra is: know your cable. Thus, the book begins with a comprehensive overview of power cable design and manufacturing through the ages, and then: Describes the characteristics of the materials currently used in the production of various power cables Explains how to calculate the die orifice for drawing wires, how tolerance in manufacturing affects material weight and consumption, and how and why lubricants are used Addresses the formation, stranding, and insulation of the electrical conductors, as well as the sheathing, armouring, and protective covering of the power cables Delivers an in-depth discussion of quality systems, quality control, and performance testing Covers the many nuances of cable installation, including laying, jointing, and terminating Throughout, the authors emphasise consonance between design theory and practical application to ensure production of a quality power cable at a reasonable cost. They also underscore the importance of careful handling, making Power Cable Technology a must read for power cable engineers and technicians alike.
From the more basic concepts to the most advanced ones where long and laborious simulation models are required, Electromagnetic Transients in Power Cables provides a thorough insight into the study of electromagnetic transients and underground power cables. Explanations and demonstrations of different electromagnetic transient phenomena are provided, from simple lumped-parameter circuits to complex cable-based high voltage networks, as well as instructions on how to model the cables. Supported throughout by illustrations, circuit diagrams and simulation results, each chapter contains exercises, solutions and examples in order to develop a practical understanding of the topics. Harmonic analysis of cable-based networks and instructions on how to accurately model a cable-based network are also covered, including several “tricks” and workarounds to help less experienced engineers perform simulations and analyses more efficiently. Electromagnetic Transients in Power Cables is an invaluable resource for students and engineers new to the field, but also as a point of reference for more experienced industry professionals.
The demand for high-performance submarine power cables is increasing as more and more offshore wind parks are installed, and the national electric grids are interconnected. Submarine power cables are installed for the highest voltages and power to transport electric energy under the sea between islands, countries and even continents. The installation and operation of submarine power cables is much different from land cables. Still, in most textbooks on electrical power systems, information on submarine cables is scarce. This book is closing the gap. Different species of submarine power cables and their application are explained. Students and electric engineers learn on the electric and mechanic properties of submarine cables. Project developers and utility managers will gain useful information on the necessary marine activities such as pre-laying survey, cable lay vessels, guard boats etc., for the submarine cable installation and repair. Investors and decision makers will find an overview on environmental aspects of submarine power cables. A comprehensive reference list is given for those who want further reading.
